The GT Grade Tiagra gravel bike can handle a little bit of everything you throw at it. Never before has a high-tech road bike been so capable on low-tech roads. The Grade is ready for everything, from freshly-paved switchbacks along mountain roads to the gravel roads you ride; and everything in between. The Grade knows no bounds. "The Grade is designed to be a road bike, adventure bike, and gravel bike wrapped up into one versatile package. After two days riding it in the Wasatch Mountains, I think GT nailed it." - Ron Koch, Bicycling Magazine.

The secret of the Grade's success lies in the unique frame design. GT took their famed triple triangle design and updated it for all-day adventures on rough roads. The main frame is made from GT's Enduroad carbon fiber for a stiff, lightweight ride that's as fast as it is comfortable. The seatstays, however, are actually made of a revolutionary fiber glass composite that helps smooth out the ride and improve vibration dampening for a more comfortable ride on even the harshest roads. And don't worry about how skinny they look--they might look a little delicate, but they're anything but. The full carbon fiber features 15mm thru-axle dropouts for improved stiffness and better compatibility with the included disc brakes.
